Getting env vars to work in MCP client

[philippgille]

The example config contains this:

mods/config_template.yml

Lines 12 to 22 in bee8b17

	# github:
	# command: docker
	# env:
	# - GITHUB_PERSONAL_ACCESS_TOKEN=xxxyyy
	# args:
	# - run
	# - "-i"
	# - "--rm"
	# - "-e"
	# - GITHUB_PERSONAL_ACCESS_TOKEN
	# - "ghcr.io/github/github-mcp-server"

But (using a different MCP server) I can't get it to work. It seems to pass the literal string (in the example GITHUB_PERSONAL_ACCESS_TOKEN) as arg, instead of replacing it with the value from the env.

I checked the code and can't find it resolving the env var. Is that missing? Or am I doing something wrong?
